Aria dragons are a brightly-colored and sprightly breed, perhaps most adored for their lyric calls. Their song-like melodies fill the areas they inhabit; their coos resemble those of birds, only more elegant and refined. They have fairly strong magical capabilities, but tend to reserve these strengths for last-minute defense, choosing to live their lives in simple peace. Arias, sticking to the tropics, typically live quite far from human settlements, giving rise to the previously held belief that they had gone extinct.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Rosa lived a very uneventful life for a female dragon till "The Wandering Away" of her owner in a dangerous journey. Around the same time, news arrived of the unknown spell that prevented any more Bright Pink dragons to be born. She then fell into a deep melancholy, and had to be taken care of by her frozen daughter Winter Rose. In time, other dragons of her cave started to notice and told her tales of what other wanderers had heard about the owner's long journey. The owner was alive, though far away, and this gave her hope amidst the sadness. As the owner recently returned, Rosa is gradually getting more joyful and spontaneous, and recently started thinking of mating again and have a light pink little dragon.
